The Doctor needs to return to Gallifrey but, because of Romana's action in the previous adventure, he is dreading the paperwork and official inquiry. Instead he convinces Adric they should stop by Earth to take some measurements of a police box before heading to Logopolis to have repairs completed to the Chameleon Circuit. Arriving on Earth the Doctor senses something wrong. A time bubble has formed, causing a TARDIS to appear within a TARDIS. The Doctor fears it's an infinite regression. If so, he and Adric will be trapped forever. Meanwhile Tegan, an Australian airline hostess, enters the Doctor's TARDIS after her car breaks down. Written by glen_chapman

Did You Know?


Christopher H. Bidmead, a keen computer enthusiast, used many ideas from computer science in developing the story, with elements such as the Monitor, block transfers, and registers all being derived from terminology in computer architecture. Eager to inject Doctor Who with real scientific notions, Bidmead also drew upon the physics discipline of thermodynamics, making heavy use of the concept of entropy: the measure of unavailable energy in a system, which effectively increases as a system becomes homogeneous. Another starting point was Nathan-Turner's observation that a real police box still stood on the Barnet bypass in London. Bidmead was fascinated with the TARDIS, and wanted to explore its properties more fully. See more »


Adric: Doctor?
The Doctor: Look, whenever you see me in this part of the TARDIS, pacing up and down like this, be a good chap and don't interrupt me, will you, unless it's terribly urgent? It's not terribly urgent, is it?
Adric: Well, no.
The Doctor: So now you know. In fact, there's no need for you to come barging in here at all. If it is terribly urgent you could always ring the cloister bell.
Adric: The cloister bell?

Right Off A CLIFF
21 October 2015 | by (Camden, NJ (The Forbidden Zone)) – See all my reviews

In my latest DOCTOR WHO marathon-- this time, watching the individual episodes for the 1st time since the 80s (I have "Inferno" up to "Terminus" that way). I just reached the point where I was painfully reminded that the writing FELL RIGHT OFF A CLIFF.


I swear... Christopher Bidmead is like the exact opposite of Eric Saward. He's a MUCH better story editor than he ever was a writer. Plus, this was his first of ONLY 3 scripts he ever did on his own. And it was a rush job. What you get is a mixture of fascinating ideas... and REALLY terrible characterization and dialogue. Tom Baker, Mathew Waterhouse, Sarah Sutton, Anthony Ainley... all were wonderful in "The Keeper Of Traken". Yes, even "Adric". And NONE of them come off good in this one. In fact, more than ever before, I was reminded of what a WONDEFFUL character "Tremas" was... so intelligent, reasonable, warm... he deserved better. He deserved a return appearance... not to be MURDERED so that a ONE-dimensional erratic bad parody of Roger Delgado should take his place.

Frankly, I think they only come off looking acceptable because Janet Fielding-- who I KNOW is a nice person off-camera-- came across as such a TOTAL B**** as "Tegan" (my LEAST-favorite WHO companion of all time).

I swear, the ONLY actor in this who comes across well in this is, surprisingly, John Fraser as "The Monitor".

Looking back, I wish to God that John Nathan-Turner had left after this one year. Because I KNOW... as wonderful as Peter Davison is as a person and as an actor... the BULK of his 3 years was EVEN WORSE than this. BAD writing, BAD directing, BAD acting across the board.

This time around, I've been skipping any stories I just don't like. I managed to get all the way through Tom Baker's 7 years and ONLY skip one single story (one that I simply have seen too damn many times for something that horrifically downbeat and disturbing). I'm wondering if I'll even watch HALF of Davison's stories? I know one thing... as soon as I'm done with his, I'll be pulling out CAMPION to watch again. Man, I LOVE that show!!!
